Given :- complete the following activity to find the length of median AD
A(-1, 1) , B(5, -3) , C(3, 5) ?
Solution :-
since AD is median, it will bisect side BC .
Let us assume that the coordinate of D are (x , y) .
so,
→ x = (5 + 3)/2 = 8/2 = 4
→ y = (-3 + 5)/2 = 2/2 = 1 .
then,
→ AD = √[(x2 - x1)² + (y2 - y1)²]
→ AD = √[{4 - (-1)}² + (1 - 1)²]
→ AD = √[(4 + 1)² + 0²]
→ AD = √(5)²
→ AD = 5 units (Ans.)
Hence, Length of Median AD is 5 units.
